Substitute Part Grouping Explanation

Substitution of the S9S12VR48F2VLF is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: 12V1 core
• Memory Configuration: 48KB FLASH, 512 bytes EEPROM, 2KB RAM
• Operating Frequency: 25MHz
• Supply Voltage Range: 3.13V ~ 5.5V
• I/O Count: 28 pins
• Connectivity Interfaces: IrDA, LINbus, SCI, SPI
• Peripheral Functions: LVD, POR, PWM, WDT
• Package Format: 48-LQFP (7x7)
• Temperature Range: -40°C ~ 105°C
• Data Converter Specification: A/D 6x10b

The S9S12VR48AF0VLF meets all these parameters identically, establishing it as a direct functional equivalent. The primary distinction between these parts is product status: the S9S12VR48F2VLF is obsolete, while the S9S12VR48AF0VLF maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The S9S12VR48AF0VLF is the direct equivalent for the obsolete S9S12VR48F2VLF. Both devices are manufactured by NXP USA Inc. and share identical electrical, mechanical, and functional specifications. The S9S12VR48AF0VLF maintains active production status with significantly higher inventory availability (17,700 units versus 1,210 units for the obsolete variant). Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support. The identical 48-LQFP package format and pinout enable direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)
